How to run a fair 90-day probation review (a simple checklist)

The 90-day probation review is one of the most useful moments a small employer has with a new hire — and one of the most often skipped. Do it well and you catch problems while they're still fixable, you give a good new hire real momentum, and you end up with a clear record everyone signed off on. Skip it, and you find out someone wasn't working out the way most small businesses do: months later, the hard way.

Here's how to run one that's fair, useful, and documented — in plain language, no HR degree required.

What a probation review actually is

It's a structured check-in near the end of a new hire's first stretch — commonly 90 days, though 30/60/90 checkpoints are common too. The manager reviews how things are going against the expectations of the role, the employee gets to share their side, and you land on a clear outcome: they're a fit, they need a bit more time, or it isn't working. Then you write it down.

The checklist

1. Put it on the calendar from day one. Set the review date the moment someone is hired, counting from their start date. The most common failure isn't a bad review — it's no review, because nobody scheduled it.
2. Use the same questions for everyone in the role. Consistency is what makes a review fair. Two line cooks should be measured against the same expectations, so the outcome reflects the work, not who the manager likes.
3. Focus on specific, observable behavior. "Shows up on time and ready," "follows the closing checklist," "handles a frustrated customer calmly" — not "bad attitude." Specifics are fairer, more useful to the employee, and far easier to stand behind.
4. Make it two-way. Give the employee a chance to share how they think it's going before or during the review. New hires often know exactly where they're struggling — and a self-assessment turns the review into a conversation instead of a verdict.
5. Be clear about the outcome and next steps. End with an unambiguous result — pass, extend, or not a fit — and, if they're staying, one or two concrete things to keep doing or improve. Nobody should leave a probation review unsure where they stand.
6. Put it in writing and have them acknowledge it. A signed acknowledgment isn't about being adversarial — it confirms the conversation happened and was understood. Keep a copy. If your team works in more than one language, make sure the employee reads and signs in the language they actually speak.

Common mistakes to avoid

• Surprises. A probation review should confirm feedback the employee has already heard, not deliver news for the first time.
• Vague feedback. "Do better" helps no one. Tie everything to something observable.
• No record. A review that lives only in a manager's memory can't help you be consistent — or show that you were fair.
• One language for a two-language team. If someone did the work in Spanish, a review they can't fully read in English isn't a fair review.

Where a tool helps

You can absolutely do all of this with a calendar reminder and a document. A tool earns its keep by removing the two steps that get dropped: scheduling (Supera auto-schedules the probation review from the hire date, so it never slips) and the record (a tailored, bilingual review form, a signed acknowledgment, and a clean copy on file). Everything above — consistent questions, specific wording, a two-way flow, a clear outcome — is built into how it works.
